My parents make these fish tacos all the time and I am finally getting around to share the greatness that is Blackened Fish Tacos with all of you. Gotta love those good family recipes!

I wish I could share a taco with each of you to show all of you how amazing they are – but the technology isn’t there yet. I’m hoping scratch & sniff screens are in the near future!

These fish tacos are absolutely divine and I don’t say that lightly. I am always on the hunt for a good fish taco and try them at restaurants all the time…and these are better than 98% of them.

The method of cooking your fish in a cast iron skillet with a bunch of butter is brilliant and gives it that perfect texture and crispy outside. You want to find a good blackening seasoning. 

And the sauce on these, oh I could write a song about this fish taco sauce. It seriously has all my favorite flavors in it and I love that you get creamy and slightly spicy all in one yummy sauce. Oh and it has lime and cilantro in it. BEST EVER.

Fish Taco Sauce

  • Juice of 1/2 a lime
  • 1/2 cup sour cream
  • 1/2 cup mayo
  • 1 tablespoon garlic salt
  • 1-2 chipotle peppers in adobo sauce, to taste
  • 1/2 cup roughly chopped fresh cilantro

Blackened Fish:

  • 2 tablespoons olive oil
  • 2 pounds white fish fillets (or any white fish you like), cut into 1 inch thick fillets
  • 1 stick unsalted butter, melted
  • 3 to 4 tablespoons seafood blackening seasoning

Fish Tacos:

  • corn tortillas, warmed
  • shredded cabbage/coleslaw mix

  2. Blackened Fish: Preheat oven or grill to 400°F.
  3. Coat cast iron skillet with olive oil. Place cast iron skillet in heated oven (or grill) for 10 minutes to get it nice and hot.

    I followed this recipe, and I think the grill temp may be a little high. My fish were vaporized as soon as they went in. I’ll try again after I catch some more fish.

    Um. . . . . . . I just ran across this recipe. Has anybody realized the temperature for the Grill? Mine melted when I got it to 2500°F. What did you guys do to get it to the rec’d 4000°F cooking temperature? Also, how did it taste? I’d imagine it’d be a bit um. . . . . toasty.

    Hi, Jessica! I am making this tonight for the family. I just wanted to get a confirmation on the ‘Tablespoon of Garlic Salt.’ seems like a lot of salt for a small amount of sauce.

    1. Jessica

      Hi Julie! I do use 1 tablespoon of garlic salt int he sauce, but you can definitely start with a little less and taste and see as you go! 🙂

    I was looking for a fish taco recipe and I found this is my search… what a sweet story!!!!
    Thanks for sharing… and thanks for the recipe 🙂

    Your sweet story really hit home. I rescued the single best dog in the whole world about 7 years ago, when he was approximately 6 years old. He is really starting to decline and the thought of losing him just breaks my heart. I know he can’t live forever and I have been so blessed to have him but I just don’t know how I will handle his loss. I loved your story and will remember it when the time comes. Thank you for sharing your story – and your fish tacos recipe.

    You made me cry! That is an awesome story.

    I’m new to your sight – – Happy One Dayaversary to me! I love it! I am a self taught cook (thanks Food Network) and I am always looking for new recipes. I can’t wait to try yours.

    I have a kitten, Sheldon, who is the furry son I never knew I needed. He’s a big eater, so I think he was sent to me for a reason. Enjoy your baby. ^..^

    Your post made me cry (and I’m at the office!!!) and then it made me smile, because I love it when people adopt baby cats and then they grow into beautiful and happy adult cats! I have a cat myself who “arrived” at my place shortly after a street cat I really loved died, so I know the feeling…
    …oh, and I also love fish tacos. Almost forgot to tell you that =)

  9. Samarie

    Congratulations on your new kitty!! I recently lost a kitty so I know your pain. They truly are beloved family members. Take care of that precious little baby sent to you from the heavens.

  11. Sarah

    I have been having a hard time with my fish tacos because the juice leaks through the corn tortillas. I can’t wait to try your recipe! P.S. I LOVE your cat story and the meaning behind it. What a great page to stumble upon! God bless you and your family.
